Do ARRAYS Secretly CHANGE Themselves? | Mutability of Arrays | Less Known Java Principles | Ep 01
Did you know Arrays secretly change themselves?
In this video, we break down one of the most misunderstood behaviors in Java — array mutability. If you’ve ever passed an array into a method and noticed it changed outside the method too, this is why.
In this video you’ll learn:
What mutability actually means in Java
Why arrays behave differently from primitives
How references work under the hood
Common bugs caused by accidental mutation
How to avoid unwanted side effects in your code
I’ll walk you through a simple example so you can see exactly what’s happening behind the scene.
